Roughness based study of milled composite surfaces

Abstract

This work reports on the results of a study of the surface roughness of Carbon Fiber based composite sheets after a milling process carried out with WC circular inserts partially covered by PCD (Polycrystalline Diamond). An analysis based on the influence of the cutting parameters has been achieved. Results obtained from this analysis have shown that surface roughness of the machined samples have high dependence on cutting depth. A parametric model has been proposed for establishing a relationship between average roughness, Ra, and cutting depth, d.
